Title: Bubble removal method at head for ink jet recorder
Inventor: SHIMURA MICHIO
IPC: B41J2/175
Filed: 1978-11-06
Abstract: PURPOSE:To separate dirts or the like in the nozzle section and bubbles attached to the ink chamber wall easily and accurately away from the walls by giving vibration to the ink jet head with a vibrator put thereon. CONSTITUTION:Ink chambers 3 and 5 are provided inside a nozzle 4 for injecting ink and with the pressure applied to the ink in the ink chambers, the ink is injected to the recording surface. A vibrator 11 is pressed in contact with the front of a head thus arranged by means of a spring 13 so that it is vibrated by an ultra sonic wave at a resonance frequency. Consequently the front plate 1 of the head is caused to vibrate and forcedly separate bubble A, dirts and deposits of the ink away from the front plate 1. Then, they are isolated in the ink in an outer chamber 3 and discharged to a discharge port 9 on the flow of the ink. The surface of the vibrator 11 is covered with a coat of resin 12 or the like to repel water.

IPC: G11B5/31
Filed: 1990-05-25
Abstract: PURPOSE:To easily form a specified gap depth of a thin film magnetic head with high accuracy by detecting the specified gap depth when each resistance between 1st and 2nd terminals and between 2nd and 3rd terminals is infinite. CONSTITUTION:A resistive pattern 33 having 1st and 2nd terminals 32a, 32b and a resistance sensor 22 comprising an inter-layer insulation layer and a 3rd terminal 32c are formed. Then the resistance sensor 22 and the gap depth of the magnetic head are polished simultaneously and the specified gap depth is detected when the resistance between the 1st and 3rd terminals 32, 32b and the resistance between the 2nd and 3rd terminals 32b, 32c are infinite. Thus, even when mask mis-alignment of the resistance pattern 33 takes place, the gap depth is detected with high accuracy.

Abstract: PURPOSE:To improve the yield in production by increasing the transmittance of light of a light source, such as back light, and decreasing the density of wirings of matrix electrodes of the liquid crystal display device in constituting the liquid crystal display device. CONSTITUTION:Liquid crystal layers 1y, 1m, 1c of yellow magenta, cyan having absorption wavelength bands controllable to wavelengths of blue, green and red are superposed in three layers in a direction orthogonal to the transmission direction of light and the absorbances of the respectively corresponding wavelength bands are controlled independently with the respective layers. Color display is then executed by subtractive color mixing. The higher transmisstance of light than in the case of the conventional additive color mixing using color filters is attained for the subtractive color mixing with the multi-layered liquid crystal. The efficiency of the light source is improved and the display with high brightness is made possible. Simultaneously, the three primary color display circuits which are heretofore realized by plane wiring are replaced with three layers of the independent display circuits, thereby, the packaging density is lowered and the yield of production is improved.
